Trailblazer P0340 - Cam sensor test and replace
This is not a P0340 tutorial. This is what it took to convince me that the cam sensor in my 03 needed to be replaced. Doing the other tests that I did prior to this test would have made this video run way too long. The 5v and ground circuits were verified, it passed the tap test, cam count never dropped on the Tech2, so watching the cam sig was the next step. I have to admit I got lucky here. I only saw the glitch twice. With the problem being so intermittent I was expecting to have the drive the truck with the equipment hooked up to catch it. For you folks at home, if you want to gamble $26 on an AC Delco cam sensor, statistics are on your side....but don't expect a fix. Again, this isn't a tutorial. Just like the case I talked about, they banged in a sensor based on the P0340 only and when that didn't fix it, it went to a shop. I just don't want to give anyone a false hope that banging in a sensor will fix the problem. And there are way too many possible root causes to have them all in one video. Cam sensor bolt torque: 89 INCH/lbs. Update August 2013 - The first line of the description says that this is not a tutorial. If you snorted your months supply of ADD mediation by the fifth of the month and can't watch an entire video, kill yourself. The sensor replacement is only a small part of the video.
